The text is a bit hard to read. The font size feels a bit small, and a larger game window could help, such as enabling Itch's option for adding a fullscreen button, as long as your game can auto-scale. I used the browser's zoom to make things more readable. In addition to the font size, the messages in game saying what you can do, such as roll the die and "You can Continue Forward" could use with more contrast, such as adding a background panel around the text. It doesn't have to be solid. a semi-transparent background could add just that little bit of extra contrast to help with readability. Pressing space to see the map there is nice contrast with the black background, but the distance scaling makes the small font size even harder to read, and even zoomed in I could only just read the nearest tiles.
The turn swap feels a bit bright compared to the main game and could be problematic for some people, especially if playing in a dark room. It also feels a bit longer than needed as the game progresses. There is no need for a player to look away, so a shorter swap would be fine.
It would be nice if there was something showing when you gain or lose money how much it was. You get a sound and your total changes, but then it quickly shows the turn swap screen. Similarly, when asking to upgrade a panel, it would be nice if it showed how much the opponent would currently be charged. Yes, you can press space to see tile info, but having it in the dialog such as "Pay X to increase visit cost from 30 to 50" would be nice.
The controls are not great. It would be nice if you added support for keyboard movement with arrow keys or WASD, in addition to the on screen buttons. You use space for the board info view, but possibly changing that to another key and allowing space or enter for confirming options.
I played both characters and bought up about half the board. It got a bit repetitive. The controls and turn swap delay just didn't work for me. It does have a bit of the classic game feel, so there is a bit of nostalgia there for some people. The concept is decent, it just needs some work to make it feel more enjoyable.
